Answer for Class 12 Biology Students
Human Male Testes:
Testes are extra- abdominal, situated outside the abdomen in a pouch called scrotum.
Scrotum helps maintaining the low temperature of testes (2- 2.5° C lower than normal internal body temperature) necessary for spermatogenesis.
Testes are covered by dense white fibrous capsule called tunica albuginea.
The capsule extends inward forming septa that divide each testis into a series of compartments called lobules.
Each lobule contains one to three highly coiled seminiferous tubules in which sperms are produced by the process called spermatogenesis.
Seminiferous tubule is lined by two types of cells: male germ cells (spermatogonia) and Sertoli cells.
Spermatogonia undergo meiotic division to form sperms.
Sertoli cells provide nutrition to the germ cells.
The region outside the seminiferous tubules called interstitial space which contains blood vessels and interstitial cells or Leydig cells.
Leydig cells secrete male sex hormones called androgens.
